The invention is directed to a droplet actuator device and methods for integrating gel electrophoresis analysis with pre or post-analytical sample handling as well as other molecular analysis processes. Using digital microfluidics technology, the droplet actuator device and methods of the invention provide the ability to perform gel electrophoresis and liquid handling operations on a single integrated device. The integrated liquid handling operations may be used to prepare and deliver samples to the electrophoresis gel, capture and subsequently process products of the electrophoresis gel or perform additional assays on the same sample materials which are analyzed by gel electrophoresis. In one embodiment, one or more molecular assays, such as nucleic acid (e.g., DNA) quantification by real-time PCR, and one or more sample processing operations such as sample dilution is performed on a droplet actuator integrated with an electrophoresis gel. In one embodiment, an electrophoresis gel may be integrated on the top substrate of the droplet actuator.

Analysis system (10, PROSAD) for the quantitative chemical analysis of samples (A, A-1, A- 2,....), preferably but not solely in the medical field, comprising detection instrumentation or equipment (30) designed to detect the quantity of the target analytes ( [x], [y], [z] ) present in the various samples (A, A1) to be analysed, which in turn comprises a chromatography system (31), an ion source (32) and a mass spectrometer (33); a data processing system (40, 42, 43, 44) designed to process the quantitative data of the target analytes present in the samples analysed, as detected by the detection equipment (30); and an innovative database (41) containing corrective and control data and coefficients (K, C, K1) to be used to calibrate and correct the instrumental response of the specific detection equipment (30) used to analyse the samples, wherein said corrective and control data and coefficients are determined and acquired by the database at a preliminary stage (51, 52) before the actual analysis of the samples, wherein the sample to be analysed is prepared with a universal dilution solution in order to minimise the corresponding matrix effect, and wherein the data processing system determines the quantitative data of the target analytes present in the samples analysed by processing the quantitative data (Q) detected by the detection equipment, namely the mass spectrometer, taking account of the corrective and control data and coefficients contained in the database. By comparison with the analysis systems currently in use, the system for quantitative analysis of samples according to the invention presents the significant advantage of not requiring, in order to calibrate the detection equipment during the analysis of multiple samples, continuous and expensive use, for each analysis, of commercial standards of the target analytes to be quantitated.

The invention is suitable for blood analysers.

The present invention discloses a topological graph-based intelligent navigation method and system, and relates to the field of computer technologies. A specific implementation manner of the method comprises: determining a navigable area view based on a constructed topological graph according to current position information; obtaining scene data, wherein the scene data comprises at least a scene image, a scene depth map, and a scene analytical diagram; and determining a behavior decision according to the navigable area view, the scene data, and a navigation model. The method is based on a multi-index navigation model, and the navigable area view is determined based on the constructed topological graph. Compared with a mapless mode, the method can be used to improve real-time navigation accuracy under the constraint of a GPS, and improve navigation robustness with incomplete dependence of the GPS.
